CUSPIDOR Filed June 5. 1934 Invenlor Blf Patented Nov. 27, 1934 UNITED STATES anni PATENT OFFICE 3 Claims.

" ing a novel construction, combination and arrangement of parts through the medium of which the spilling of the contents will be prevented should the cuspidor be accidentally tipped over, Vas frequently happens.

Other objects of the invention are to provide a cuspidor of the aforementioned character which will be comparatively simple in construction, strong, durable, reliable in operation, compact ,4 and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following speciication, taken in connection with the accompanying drawing wherein like characters of reference designate corresponding parts throughout the several views, and whereinz- Figure 1 is a Vertical sectional view through a cuspidor constructed in accordance with the `present invention.

Figure 2 is a detail View in perspective of the shield which is mounted on the valve stem.

Figure 3 is a horizontal sectional view, taken substantially on the line 3-3 of Figure 1.

Figure 4 is a view in horizontal section, taken substantially on the line 4--4 of Figure 1,

Referring now to the drawing in .d etail, it will be seen that the embodiment of the invention which has been illustrated comprises a container including a body 1 of the usual shape having a substantially conical top 2 which is provided with a discharge opening or passage 3. The container further includes a bottom 4 which, if desired, may be weighted in the usual manner.

Rising from. the bottom 4 is a centrally located, -vertical tube 5 which is open at its upper and lower ends, said tube passing through the bottom a and being xed therein. Mounted for sliding movement in the tube 4 is a stem 6 having threadedly mounted on its upper end a valve '7 which is adapted to seat in the restricted lower portion of the substantially conical top 2 in a manner to close the opening 3. The lower end of the stem 6 is engageable with the floor or other surface upon which the cuspidor may be resting for maintaining the valve 7 in its normally open position. Lock nuts S secure the valve 7 against rotation on the upper end of the stem 6.

Also fixed on the stem 6, below the valve 7, is a cross arm 9 having downwardly curved end portions terminating in eyes 10 to which one end of a pair of coil springs 11 is connected. The other ends of the coil springs 11 are connected, as at 12, to the bottom 4 of the cuspidor.

The reference numeral 13 designates a suitable packing on the upper end oi the tube 5 which prevents leakage around the stem 6. The reference numeral 14 designates a substantially conical shield for the packing 13, etc., which is mounted on the valve stem 6 below the cross arm 9. Y

vIt is believed that the operation of the invention will be readily apparent. When the cuspidor is in its normally upright position the stem 6 is, as hereinbefore stated, engaged with the floor or other surface upon which the cuspidor is mounted and in this manner the valve 7 is maintained in open position against the tension of the coil springs 1l, as illustrated to advantage in Figure l of the drawing. Should the cuspidor be tipped over or lifted, the coil springs 11 pull the stem 6 downwardly in the tube 5 and seat the valve 7 in the restricted lower portion of the substantially conical top 2 in a manner to effectively close the opening or passage 3 to prevent the discharge therethrough of the contents of the container l.

It is believed that the many advantages of a cuspidor constructed in accordance with the present invention will be readily understood, and althoughfa preferred embodiment of the invention is as illustrated and described, it is to be understood that changes in the details of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.

What is claimed is:-

l. A cuspidor comprising a container including a body, a bottom, and a substantially conical top having a discharge opening therein, a tube rising from the bottom, a stem slidably mounted in the tube and engageable with the surface upon which the cuspidor is mounted, a valve mounted on the upper end of the stem and engageable in the substantially conical top for closing the passage, a cross arm mounted on the stem below the valve, and coil springs connected, at one end, to the cross arm, and at their other ends to the bottom of the container for seating the valve when the stem is disengaged from the supporting surface upon which the cuspidor is resting.

2. A cuspidor of the class described comprising a container including a body, a bottom, and a substantially conical top having a discharge opening therein, a centrally located tube rising from the bottom, said tube open at its upper and lower ends, a stern slidably operable in the tube and engageable with the supporting surface upon which the cuspidor is mounted, a valve threaded- 1y mounted on the upper end portion of the stem and engageable in the substantially conical top for closing the opening therein, a cross arm mounted on the stem below the Valve, coil springs connected, at one end, to the cross arm and at their other ends to the bottom of the container for yieldingly urging the valve toward closed position, a packing gland on the upper end portion of the tube for preventing leakage around the stem, and a substantially conical shield for
